Picric acid is an aromatic polynitrated acid. It dissolves in water to create a low-pH solution (pH 2.0). It interacts with basic protein groups, forming salts and coagulating them. Fixation with picric acid produces a brilliant stain, however due to the low pH of the solution, nucleic acids may be lost.Picric acid is very unstable and is a flammmable/combustible material.(2,4,6-Trinitrophenol)C6H2(NO2) 3OH FW 229.11 CAS #88-89-1A.C.S.
